Peb nqa ib khub Vittoria's Qurano 60 lub log thiab Corsa G log tsheb los caij Strada Bianchi hauv Ltalis. Thiab txaus siab heev
Zaj dab neeg luv luv, graphene yog cov khoom xav paub tshiab thiab koj yuav tsum tau muab tso rau hauv txhua yam ntawm koj lub tank roj av rau koj cov cereal, uas yog vim li cas Vittoria tau muab tso rau hauv nws cov Qurano 60c log tshiab thiab Corsa G log tsheb.
Kuv tsis nkag siab tag nrho (pom tias nws tau tshawb pom siv mem hluav thiab qee qhov Sellotape), tab sis lub tswv yim yog tias graphene ua rau cov khoom sib zog, muaj zog thiab zoo dua.
Nyob rau hauv cov ntaub ntawv ntawm Qurano 60s uas txhais tau hais tias ib txheej ntawm 60mm-dav, 24.5 hli dav, tag nrho-carbon hoops hnyav ib tug thov 1,570g. Qhov twg yog qhov zoo tshaj plaws. Zipp qhov tseeb NSW 404s, ntawm 58mm, hnyav 1, 555g, thiab Bontrager's Aeolus 7 D3s yog 1, 610g (txawm tias lawv tob 70mm, 50mm Aeolus 5s yog thov 1, 440g). Tsis tas li ntawd, nyob rau hauv lub tswv yim loj ntawm high-end log, Quranos pheej yig - £ 1, 600 piv rau £ 2, 150 rau Zipps thiab £ 2, 200 rau Bontys.
Zoo li cov log, Quaranos nrawm, tiag tiag los rau hauv lawv tus kheej siab dua 32kmh. Nws yog raws li kuv Garmin-gazing anecdotal pov thawj, tab sis yav dhau los uas ceev Quranos muab kuv ntawm 2 thiab 5kmh dawb, mus txog rau ib ncig ntawm 48kmh. Ntawd yog, lawv tau nrawm dua rau tib lub zog pedaling piv rau qhov hnyav hnyav sib xws.
Qhov ntawd tsis yog qhov tshwj xeeb rau Quranos - lwm qhov sib sib zog nqus yuav them cov nyiaj faib zoo sib xws - txawm li cas los xij qhov tseeb yog lawv nrawm npaum li cas thiab lawv ua tau zoo npaum li cas hauv crosswinds. Qhov loj gusts tseem yog ib yam dab tsi uas yuav tsum tau nco ntsoov raws li ib tug high-sided wheelset, tab sis nyob rau hauv lub ntsiab lawv yog incredibly ruaj khov, tuav lawv tus kheej tshwj xeeb tshaj yog zoo ntawm ceev, cua qhovntsej thiaj tsis mob. Tsis wobbles, tsis muaj wrestling nrog tswj.
huab cua qhuav braking tau zoo heev, thiab txawm tias huab cua ntub yog qhov tsim nyog; tsis yog nyob rau theem ntawm disc brakes los yog cov uas tshwj xeeb machined alloy braking nto, tab sis kwv yees thiab nce txaus kom muaj kev nyab xeeb. Txawm li cas los xij, nws yog Qurano qhov ruaj khov uas ua rau kuv zoo siab tshaj plaws, uas coj kuv mus rau Vittoria's Corsa G tyres tshiab…
Hardnosed performance
Kuv tsis tau loj hlob nrog tubulars, thiab vim li ntawd kuv nyob hauv qhov xwm txheej ntawm cov hnyuv ntxwm tsis kawg. Tubs muab peb lub caij zoo tshaj plaws tab sis lawv luag ntawm peb cov khoom siv kho mob, hnab nyiaj thiab ua siab ntev, ham-fisted gluing. Luckily, ho, qhib tubular log tsheb (tseem ceeb unsewn tubs uas ua hauj lwm zoo li clinchers) yog nyob ntawm tes los muab ze tub-zoo li kev ua tau zoo nyob rau hauv ib qho yooj yim rau nruab, kho pob. Txawm li cas los xij, muaj qhov downside - qhib tubs paub tias hnav ntau dhau. Txog thaum, reckons Vittoria, koj sib tov hauv qee cov graphene.
Kom sim lub tswv yim no kuv xav tias kuv yuav coj Corsa Gs los caij cov neeg nyiam ua si Strade Bianche - 130km ntawm punchy chalk nce thiab txoj kev pob zeb tsis sib haum. Thiab tsuas yog ua kom lom zem, kuv xav tias kuv tuaj yeem muab lawv tso rau hauv Quranos.
Thaum pib kab kuv tseem muaj kuv qhov kev tshwj tseg, tab sis los ntawm thawj ntu ntawm pob zeb kuv paub tias kuv tau xaiv qhov zoo, thiab thaum kawg ntawm kev sib tw kuv yuav tsis tau hloov lub teeb rau lub ntiaj teb..
Ntawm 25mm dav, los txog ib yam dab tsi ze 27mm mounted ntawm Quranos, Kuv xav tias kuv tuaj yeem zoo siab khiav Corsas ntawm 90psi yam tsis muaj kev ntshai ntawm pinch-flats, thiab yog li nws tau ua pov thawj. Lub siab qis txhais tau tias txhim kho tuav - tsis yog tias Corsas 'tread compound zoo li luv luv ntawm qhov no - thiab tseem muaj caij zoo. Zoo, raws li kev nplij siab li 40 kmh tshaj cov pob zeb xoob puas yuav ua tau.
Tom qab kev sib tw kuv tau tshuaj xyuas cov log tsheb kom zoo. Txawm hais tias kuv raug mob tsis pub dawb, txawm hais tias caij tsheb tsis zoo nkauj, kuv xav tias yuav pom cov cim ntawm kev hnav, qhov txawv me me txiav, tab sis tsis muaj qhov cim rau ntawm lawv. Cov tan sidewalls tsis zoo, ua kom tsaus me ntsis nrog cov av ntub dej (cov phab ntsa grey-dub muaj), tab sis lwm yam tshaj li qhov tsis zoo ntawm cov tshuaj pleev ib ce Corsas zoo li tshiab. Lub Qurano log yog ib zaj dab neeg zoo sib xws. Kuv xam pom tias tau muab qee qhov kev rau txim loj rau lawv, tab sis lawv nyob twj ywm thiab muaj tseeb.
Zoo heev
Zuag qhia tag nrho kuv pom tias nws nyuaj heev rau kev ua txhaum lub log lossis lub log tsheb. Rau cov nyiaj Quranos nyuaj rau kev yeej, thiab rau qhov kev ua tau zoo tag nrho ua ke nrog lub neej ntev Kuv tseem tsis tau tuaj hla lub log tsheb zoo dua li Corsa G. Tseem, tseem muaj chaw rau kev txhim kho.
Txawm hais tias cov duab yog xim dub ntawm cov xim dub, lub logo Vittoria indelible tsis xav tau HUGE ntawm lub log thiab yuav tsis haum rau txhua lub tsheb kauj vab. Kuv ib txwm nyiam cov ntawv nplaum uas tshem tau lossis tsuas yog dub dawb nrog lub logo me me - yog tias koj xav siv kuv li kev tshaj tawm kev tshaj tawm, koj yuav tsum them kuv, tsis yog lwm txoj hauv kev. Thiab tom qab ntawd muaj qhov teeb meem me me ntawm tubeless-ness.
Lub Quranos, foom koob hmoov rau lawv cov thom khwm carbon, yog tubeless npaj, ib qho zoo uas kuv nyiam heev thiab kuv xav tias yuav ntes tau. Tab sis Corsa Gs tsis yog. Vittoria ua ib tug tubeless version, lub Speed G, tab sis nws yog ib tug ultra-teeb (215g) lub sij hawm-sim lub hom phiaj lub log uas txo nws hwj ceev ua ntej ntawm lub neej ntev. Tsis tas li ntawd lawv tsuas muaj nyob rau hauv 23mm.
Tsis muaj ib yam ntawm cov no yog qhov cuam tshuam ntawm qhov tseeb, tab sis kuv tsis tuaj yeem pab xav tias qhov teeb meem zoo kawg li no yuav yog yog tias lub log dub tag nrho thiab Corsa Gs tsis muaj tubeless. Tseem, raws li nws muaj ntau npaum li cas los sau tsev txog ntawm no, qhia tias tej zaum yuav tsuas muaj ib yam dab tsi rau no graphene malarkey tom qab tag nrho.
